The team is now managed by former Blues boss, Andre Villas-Boas and they are believed to be keen on the Brazil midfielder.

Oscar started the first five Premier League fixtures under Antonio Conte this season, but has since lost his place in the team, playing only 36 minutes in four substitute appearances.

Villas-Boas tried to sign the 25-year-old in the summer of 2012, but he opted for a move to Stamford Bridge.

In his four-and-a-half years at the London club, he had made 99 starts in the league, but has grown frustrated recently. Oscar is understood to be willing to make the move to China and he could join his compatriots, Hulk and Elkeson at Shanghai SIPG.
